Avoid leaving water in the tank when the motor home is
not in use. Turn the water pump OFF before draining the
water tank. Whenever possible, drain the fresh water
. tarik .pefore traveling. Water in the tank will reduce the
cany!ngcapacily plthe motor home. See "Motor Home
Loading" section of the "ON
THE
ROAD" chapter.

Water Pump
The on-bpard fresh water system is pressurized by a
sell-priming, 12-volt DC pump. The pump operates
automatic~IIy
when the pump power switch is ON and a
faucet is opened. When the faucets are closed, the
pump shuts off. At free flow, the pump draws approxi-
mately7 to 7-1/2 amps, and can run dry for extended
periods without damage. A 15-ampfuse at the converter
panel protects the pump circuit. See "ELECTRICAL
SYSTEMS" chapter.
Turn the pump master switch ON to pressurize the
system. When a faucet is opened after the initial filling of
the tank, the water may sputter for a few seconds. This
. is normal and is not cause for concern. The water flow
will become steady when all air is bled from the water
lines.
, Water .Filter
Dirt, mineral scale, and organiC matter are filtered out of
the fresh water system by an in-line water filter on the
inlet side pi the water pump. " you suspect a clogged
. filter, it is easily removed and .cleaned.

Troubleshooting The Fresh Water System
Water system problems usually fall into two categories:
inherent system problems, and problems caused by
neglect. System problems are usually the result of road
vibration and campsite water pressure variations. Prob-
lems of neglect usually stem from failure to clean filters,
improper winterization, and poor battery maintenance.
Most water system problems can be avoided by consci-
entious maintenance.
Leaks
Vibration, flexing and twisting while traveling can work
pipe fittings loose. Check all plumbing for leaks at least
once a year. II the ivater pump runs when a faucet is not
open, suspect a leak. Be sure the tank drain valves are
tightly closed. Leaks occur most often around threaded
fittings. " necessary, tighten or clean and tighten the
fittings. Do not overtightenfittings. Conni3ctions at gal-
ley and lavy fixtures should not be tightened with a
wrench. They will normally seal with hand-tightening. "
a leak persists at one of the fittings, disconnect it
completely and check for mineral deposits or other
foreign matter at the seating surfaces. 'Clean the sur-
faces thoroughly and reinstallthe fitting.
Connections at the water tank, pump and valves are
made with special clamps. They can be replaced with
standard aircraft type hose clamps.
Leaks caused by freezing damage can be prevented by
proper winterization ol'lhe' system; See "STORAGE"
chapter ofthls' manuill. Freezing damage is usually
extensive and maY'inoludea burst water tank, split
piping, and a damaged water pump, toilet, and water
heater. II you experience this\ype of damage, repairs
can best be made by an authorized Fleetwood dealer.

Sanitizing The Fresh Watei' System
Sanitize the fresh water tank and piping approximately
every three months, and whenever the motor home sits
for a prolonged period. This will discourage the growth
of bacteria and other organisms that can .contaminate
the water supply. Use a chlorihelfresh water rinse as
follows:

1. Prepare a solution olll4-cup .household liquid
chlorine bleach (5% sodium hypochlorite) to one
gallon. of water for each 15. gallons of tank
capacity.
2. Close drain valves and faucets, pour chlorine
solution into the fresh water tank filler spout, and
complete filling with fresh water.
3. Turn water pump switch ON. (Be sure you have
12-volt DC power.) Open all faucets individually
until water flows steadily, then turn off. This will
purge any air from the lines.
4. Top oflwatertank with fresh water and wait three
hours.
